D is :in inlet 'pipe for t e gas which pro' jects downwardly from the top of the vessel A. 'ine pipe D connected direct to the down-comer pipe of the blast furnace, and the pipe F' is connected to the boilers or I stoves. 'The lower part A of the vessel A forms o chamber for .holding water, and is conical in form. Any approved forni of valve or closure o is provided et the bottom of the chamber ffl for letting ont the mud pericdicaliy.

B is dost chamber supported in the Ve. sei A in any approved manner, and nrov-deti with n` conical lower portion B w iclrfier ponds within the water in the Vessel A.

L ere brackets arranged between tls chambers 5i and B, and which support the chamber B.

C is o cylinder which depends from the top of the vessel A around the dust chamber E, and Wiich `forms two annuler chambers .2 and 3. Plates e are supported horizontally et the bottom oi the inner annuler chamber 2, above tiie levei of the Water in the chomber A, and E ere pipes which. de end from the nietes e so that their lower en s are nem' the Asurface of the Water. These pipes E src similar to those shown in the potent to B, J. Mullen, No. 782,041, ono'. they divide up the ges into smell .volumes in asimilar manner but any other approved Ineens can be used tor causing the ges to impinge on the pipe b haring anoutletrvslve Lof engr, op; l r

The lower part Bf Qi; the (inst chamber is provided with on ont-,Log 65'v iroveo construction. The outletegipe ,ctis charges the dust through the bottoift,oi-tigol chamber to one side of the mud-Vele,

'tiie ges in o few seconds. iw-ost of tiiissolid 95 materiel is caught by thevdnst chamber so that the Washer does not become clogged iup. The large particles of, dust and solidnwftett` are se oratori from thegas by gravity in the chem -er B, and teil upon the conical betteln B which is kept cool lby being immersed im, witter. The dry accumulations in the, chem; bei' B ire removed as often es desired by opening the valve 4. The gas With the lighter particles of dost posses into the annular chamber 2 in the direction of the arrows, and is dischargel against tbe surface of the witter through tbc pines l et o greatly reduced Velocity from tiret at which it entered the apparat-lis. The clean ges passes be-4 H0 tween the tubes E into the outer annular chamber 3, and is discharged through the ros - with an outlet for4 solid matter, a gas inlet outlet-pipe F. The gas moves the scum on the surface of the water toward the outlets H, with the assistance of the streams of water from the radial jet pipes; and the scum which enters the chamber I is carried oil' with the overflow by the outlet pipe J continuously.

What I claim is:

1. In a gas cleaner, the combination, with an outer vessel for holding cooling water, of a gas chamber inclosed in the said vessel and having an open top and a conical bottom portion which isarranged in the water-space of the said vessel andl provided at its apenr pipe connected to the top of the said outer l vessel and arranged to discharge the and solid vInattcr against the conical bottoni portion of the gas chamber, and an outlet pipe i for clean gas connected to the said outer vessel at a point below the level of the top of the gas chamber.

2. In a gas cleaner, the coinbiinition, with an outer vessel l'or holding cooling` water, of a gas chamber incloscd in the said vessel with its lower part arranged in the water-space thereof and provided with a dust-outlet, the gas spaces of the said vessel and chamber being connected at their upper ends, a gasinlet pipe connected to the top of the said outer vessel and delivering into the upper part of the said gas chamber, and means for causing the gas to impinge on the water in the said outer vessel in the space between it and the said gas chamber.

3. Ina gas cleaner, the combination, with an outer vessel for holding cooling water, of a gas chamber inclosed inthe said vessel and having its lower part arranged in the water space thereof and rovided with a dust-outlet, a cylinder depen ing from the upper part ol the said outer vessel and forming two annular gas spaces which areconnected at their lower ends above the said water-space, and a gas inlet pipe whichidelivers into the upper part of the said gas chamber, j

4. In a gas cleaner, the combination, with a gas-inlet pipe or blast-furnace downconicr, of a gas chamber having its up )er end portion arranged above and aroun the bottoin end of the said pipe and having` a dust'outlet at its lower part an outer vessel for holding cooling water which vessel incloses the said gas chamber and the lower end portion of the said pipe, said vessel b'eing lprovided with an outlet tor clean gas and a mud outlet, and a cylinder depending from the upper part ol` the said vessel and forming two annular passages, the inner annular passage conimunicating with the upper part oifthe said chamber at the top of the said cylinder, and the'outer annular passage communicating with Ithe said gas outlet and also with. the inner annular passage at the bottoni ol" the said cylinder above the water space of the said vessel.

In a gas-cleaner, the combii'iatioi., with an outer vessel for holding water provided with a conical lowei^ part inning a niudoutlct, said vessel having also an outlet ier clean gas, of a receiving chamber for the gas having a conical lower part r angcd in the. water-space of the said vessel and provided with a dust-outlet, a series of supports arranged between t ie conical lower parts of the said vessel and chamber, and ineens for causing the gas to iinpinge on the water in the said vessel.

6. ln a gas-cleaner, the conibiinition, with an outer vessel for holding water provided with a ruud-outlet and an outlet for clean gas, said vessel having also a series of scum outlets at its nornial waterdcvel, of a receiving chamber for the gas havingits lower part arranged in the water-space of the said vessel and rovided with a dust-outlet, a water supp y-pipe having a series of nozzles arranged around the said chamber and delivering streams of water toward the said scumoutlets, and means for causing the gas to in'ipinge on the water in the said vessel.

7. ln a gas-cleaner, the combination, with. an outer vessel for holding water provided with a mud-outlet and an outlet for clean gas,

of a receiving chamber for the gas having its v lower part arranged .in the water-space oi the said vessel and provided with a dust-outlct, a cylinder depending lroin the u )per part of the said vessel and overlapping t ie sait gasoutlet,plates supported between the lower part 4of the said, cylinder and the said chainber, and a series of pipes carried by the said plates and operating to cause the gas to inipingeon the surface of the water in the said vessel.

In testimony whereof I have al'lhred my signature in the presence of two witnesses. JOHN RUDD'MAN. Writnesses JOHN F. SHEPHERD, CHAs. R. BENSON.
